Had a guy, probably mid 20's, who took one of our half day seminars. It was a "hey come in for free, see what we do, then join us and learn something" event. He found out we worked pressure points and promptly informed us that they don't exist, his mom's a nurse and she told him there's no such thing, but you can pinch various veins, especially in the upper arm, to knock them out and/or kill them. Yammered about this garbage for about half an hour. . then got very angry when I suggested he conduct his own Nurse Fu seminar
